Wireless charging service system

ABSTRACT

The wireless charging service system mainly includes a wireless charging device and a server device. The wireless charging device includes a data transceiver module, a wireless charging module, and a detection module. The server device is data-linked with the data transceiver module of the wireless charging device, and a remote cloud service. A mobile device therefore may interact with the data transceiver module so that info messages prepared by the remote cloud service may be presented on the mobile device. When the mobile device is adjacent to the wireless charging device, the data transceiver module may select different info messages to present on the mobile device. Additional info messages may be added by the remote cloud service.

BACKGROUND OF THE INVENTION (a) Technical Field of the Invention

The present invention generally relates to wireless charging, and moreparticularly to a system providing wireless charging and informationservices.

(b) Description of the Prior Art

The R.O.C. Taiwan Patent No. M525019, titled “Power supplying device andpower receiving device of wireless charging system and charge controllerthereof,” teaches a power receiving device of a wireless charging systemfor performing a method of selectively wireless charging. The deviceincludes a processor and a storage unit. The storage unit stores aprogram which instructs the processor to perform the following steps:searching for a broadcast signal delivered by a power supplying deviceof the wireless charging system; determining a distance between thepower supplying device and the power receiving device according to astrength of the broadcast signal when the broadcast signal is detected;when the distance is smaller than a threshold value, the power receivingdevice selecting the power supplying device and establishing connectionwith the power supplying device, and notifying the power supplyingdevice that the power receiving device needs to be charged; and startingto receive power from the power supplying device when the powerreceiving device is determined to have a charging authorization by thepower supplying device. According to the teaching, the power supplyingdevice is able to push information to the power receiving device whilethe latter is wireless charged. However, a single piece of informationis pushed and the information content does not vary, for example,according to the distance between the power supplying and receivingdevices, or by remote control in real time. The teaching's applicabilityis therefore limited.

SUMMARY OF THE INVENTION

A major objective of the present invention is have a wireless chargingdevice capable of dynamically transmitting different messages to amobile device entering the coverage of the wireless charging device soas to achieve enhanced real-time information broadcast.

Another major objective of the present invention is to detect theproximity of the mobile device by a Bluetooth control element so that,when the mobile device is adjacent to the wireless charging device,wireless charging to the mobile device is activated. In the meantime,different messages are delivered to the mobile device under charging.

Yet another objective of the present invention is to have a servicedevice data-linked with the wireless charging device so that differentmessages may be prepared on a remote cloud service and then relayed tothe wireless charging device through the server device. As such, thereal-time information broadcast may be more flexible and diversified.The wireless charging device may also be remotely activated ordeactivated by through the server device.

To achieve the objectives, the wireless charging service system mainlyincludes a wireless charging device. The wireless charging deviceincludes a data transceiver module, a wireless charging module, and adetection module. The data transceiver module is capable of transmittingone of a number of info messages. The wireless charging modulewirelessly charges a mobile device, The Bluetooth control element of thedetection module detects whether the mobile device is placed on thewireless charging device and activates/deactivates the wireless chargingmodule. The wireless charging service system further includes a serverdevice data-linked with the data transceiver module of the wirelesscharging device for sending info messages. The server device isdata-linked with a remote cloud service. As such, when the mobile deviceenters a coverage of the data transceiver module, the mobile devicereceives an info message and presents the info message on the mobiledevice's screen. If the mobile device is placed on the wireless chargingdevice for charging, the Bluetooth control element detects the proximityof the mobile device and activates the wireless charging device to startcharging. In the meantime, the data transceiver module selects adifferent info message to transmit. The mobile device therefore mayobtain different information based on its activities.

The content of info messages or additional info messages may be editedor created by the remote cloud service. The info messages are relayed tothe wireless charging device through the server device.

Even though the prior art may also conduct wireless charging andinformation broadcast, only a single message may be transmitted and thecontent of the message cannot be changed when the mobile device is atdifferent distances from the wireless charging device. The messagecontent also cannot be modified remotely, which is quite inconvenientand troublesome. The present invention as described above resolves theseissues effectively.

The foregoing objectives and summary provide only a brief introductionto the present invention. To fully appreciate these and other objects ofthe present invention as well as the invention itself, all of which willbecome apparent to those skilled in the art, the following detaileddescription of the invention and the claims should be read inconjunction with the accompanying drawings.
